Fig; 3 is a plan view rotating disk J, all so that said disk J is free of the stand or support in the position of Fig. to be turned or,rotated in either direction up- 2. '-Fig. 4. is a detail sectional view, enlarged, on the stationary plate H of the standard 0,

50 on line a 4, Fig. 2. Fig. 5 is adctail horizon but not in either direction fora complete turn or rotation, because of the necessary abutment of the pin k of the disk J against the pin it of the ring L,that is attached, as described, to the plate H, carried by the adjustable screw-rod D of the standard 0. The fixed plate H, rotating disk J, and washer c all are open at their center, corresponding to the opening of the tubular screW-rodD and the upwardextending rod K, from the rotating disk J, and by tightening or loosening the contact of the rotating disk against said washer and fixed plate, it isplain the ease with which the rotating disk may be turned or rotated, can be regulated at pleasure, and as a consequence, while the same may be made to be freely adjustable, yet it can be made secure against accidental displacement. The upward-extend ing tubular rod K, attached to and traveling around with the rotating disk J, is at a short distance above said disk bent and broughtinto a horizontal position, as shown at M, and this horizontal part or extension terminates at the outer end in a vertical collar, N, in which is fixed a vertical rod or standard, 0, extending equally above and below said horizontal extension. The tubular rod K is also tubular in its horizontal extension l\.[, and, in fact, for its whole length, opening at Z to the outside of the vertical collar N, in which the vertical standard-rod O is fixed, as above described. This rod-standard 0 supports both a telephonic transmitter, I and a telephonic receiver, Q,

either of any of the usual or suitable constructions. This support of the transmitter and re ceiver is in each case through similar mechanism, and such being the case, a description of the mechanism of one obviously is sufficient if the proper letters be applied to the corresponding parts of the other. The transmitter I is connected to and supported from the lower end, and the receiver Q is connected to and supported from the upper end, of the rod-standard O, and the connecting and supporting mechanism of each is as follows: Eourjoints, R, S, T, and U, all of similar construction, a telescoping rod, V, and a clamp or holder, \V, each of which parts is duplicated for each telephonic instrument, transmitter I, and receiver Q. Each joint R, S, T, and Uis in three separate lifts or leaves, an n q, of a circular disk shape, and severally placed by their flat surfaces upon each other witha washer, r, (see Figs. l and 5 more particularly,) of leather or other suitable packing material, between them, and all secured together 1) ya headed screw-bolt, t, passing concentrically through their several thicknesses and screwing into either one or both of the outer lifts or disks, m g, but loosely through the middle lift or disk, a, which is thus made capable, if not bound to the disks at each side thereof by sufficiently screwing up the axial screw-bolt, of being turned or rotated upon said axial bolt. The outside disks, in and q, of each of said joints are locked together by a pin, a, fastened to one and entering loosely into a socket, 12 of the other, and located in a lug, d, ofeach disk,

which lugs project from the edge and one side of the disks, and, as a consequence, with either of said outside disks fastened or held against will be correspondingly held against movement; but if neither thereof is so fastened and otherwise they are free to be turnedthat is,

disk, 02., by means of the center or axial bolt, t, or either of them held in any other way then they, with said axial bolt, can be rotated, turning by said bolt within the center opening and by the inner face of each outside disk against the opposite faces of the middle disk. The duplicate joints R are secured one to the upper end and the other to the lower end of the rod-standard O, and in each case the several disks making each joint are horizontal and fastened to or against the ends of said standard by entering and securing the axial bolt t of eachinto the same, and, in fact, preferably the outside disk of each joint against the ends of said standard is rigidly and independently attached thereto. The middle disk of the upper joint has an angular and radial arm, 6, connecting it to an outer disk, q, of the duplicate joints S, next in order of arrangement from the rod-standard O, the middle disk, 11, of each of which joints is carried by one of the separate and duplicate telescopic rods V. Both telescopic rods V project ra dially from the axis of rotation of their respective joints, and each is composed of an outer tubular rod, if, having within it another rod, k", both of which make the telescopingrodthat is, a rod capable of being length ened and shortened-either by drawing the inner one, 76-, out of and forcing it into the outer one, h or by drawing the outer one, h off and forcing it over the inner one, k". Each I joint R rotates in a horizontal plane, and each joint S in a vertical plane, and said planes of rotation are at right angles.

One and the outer end of the inner rod, 76-,

of each telescoping rod V carries a middle disk, 41, radially attached, of one of the dupli cate joints T, next in order of arrangement from the standard-rod O, and one of the outside disks, m, of each of said joints hasa rightangular and radial arm, Z", connecting it to the middle disk, at, of one of the duplicate arrangement from the standard-rod 0. To the outside disk, on, of each of said joints U, the farther removed from the axis of rotation of the joints T, is secured one of the duplicate clamps or holders WV. of any suitable construction-for instance, the one, a ring, X, divided into two halves, secured together about the body of the receiver Q, and the other a bracket, Y, attached by screws to the under side of the transmitter P. Each joint T and each joint U rotates in a plane at right angles to the other, and the rotation of the former is in a plane coincident with the longitudinal axis of the telescopic rod 'V, to which it is connected.

turning in any manner, the other one thereof if not bound against the sides of the middlejoints U, and the next and last in the order of These clamps are each The pin a", locking together the two outside disks of each of the joints B S T U, as herein described, prevents, by the abutment against it on either side of a partto wit, the angular arm-extensions e Z, or the telescopic rods V, attached to or forming a part of and moving with the middle disk of such j ointor by its abutment against said part of the middle disk, any of said joints from having or making a complete turn or rotation in either directionabout or upon their respective axial bolts or pintles t.

The freedom with which each of the several joints R S T U may work or be worked, it is obvious, can be regulated by tightening up or loosening its axial bolt 1, or, in other words, by tightening or loosening the several disks of each joint in their bearing against each other, and plainly any of the joints may be made rigid or fast at pleasure by simply screwing up its axial bolt t sufiiciently therefor.

Electric wire connections are made with each of the telephonic instruments, transmitter 1?, and receiver Q, as usual, and in mak ing these connections the several wires pass from the instruments to and through the open endl. of the horizontal tubular rod ill, and thence through said rod, the rotating disk J carrying it, standard 0, hollow screw-rod D,'

and base-plate A to the other necessary parts to be connected.

In the improved stand or support for telephonic instruments, and attached to a table or bench, B, as herein described, it is plain that each of the instruments is capable of being adjusted in height or distance from the tablefirst, by raising or lowering the vertical screwrod D in the standard 0 from the turning of the screw-nut E; second, by swinging its telescopic rod V in a vertical direction through the joint Si of said rod V, which is connected with the middle disk, 22, of the j oint B upon the rod-standard 0; third, by swinging its clamp V in a vertical direction or plane through the joint U of said clamp, which is connected with one of the outside disks, m, of the joint T at the outer end of its telescopic rod V; and, fourth, by either lengthening or shortening its telescoping arm or rod V; and, again, each of the instruments is capable of being adjusted in its distance from a given vertical plane passing from the front to the rear, or passing across and between the front and the rear of thesupport herein described, as it is attached to the table or bench B.first, by rotating the disk J upon its support of the base-plate standard (3; second, by swinging its telescoping arm or rod V in a vertical plane or direction through the joint S of said rod, connecting it with the middle dislr. of the joint R upon the rod-standard 0; third, by swinging its telescoping arm or rodV in ahorizontal direction or planethrough its joint It, connecting it with the rod-standard O; fourth, by swinging its clamp or holder 3 \V in a vertical direction or plane through the joint T upon the outer end of its telescoping rod V, fifth, by swinging its clamp or holder WV around upon its joint U, which joint is con nected to the joint T, connected to the outer end of the telescoping arm V; sixth, by either lengthening or shortening its telescoping arm or rod V.

The adjustments of either telephonic instrument as hereinabove described, except as to those made by the operation of the screw-nut E and the rotating disk J, are independent of and separate and distinct from each other, and from the variety of the same, as appears from the recital thereof herein given, together with the adjustment secured from. the operation of said screw-nut E and said rotating disk, it is obvious that either instrument is capable of being placed in almost any conceivable position, (of course within given limits,) either as to any given vertical or horizontal plane, or as to the other or companion instrument upon the same stand or support, and therefore, as a consequence, either and both instruments can be located for most convenient, easy, and ready use, and to suit the position and condition of any operator or operators, and with the utmost case, facility, and quickness, the advantages of all of which are obvious. Limit ing the rotations of the disk J and of the sepa rate joints R S T U, substantially as described, constituting, with other parts, the stand or support of this invention, prevents all possi bility of twisting or winding of the electric wires leading to and from the instruments upon any part or parts of the stand or support to an extent to injure or damage the same, or to interfere with their proper operation at all times.

A screw-nut, E, for adjusting the screw-rod D, and operating thereon as described, together with a telephonic instrument or instruments connected to said rod, is important, in that it not only by a turning of the screw-nut in the proper direction secures the lifting and lowering of the instruments through its operation upon said screw-rod, but it also holds said instruments in their so adjusted position without further operation of any mechanism or use of any other fastening device or devices.

The horizontal extension M and the vertical rod K, to which it forms such extension, and

also both the upper and lower parts of the constructed wit-h a spline-joint, as at m", Fig.

1, to prevent them from so turning.

It is obvious, first, that the stand or support herein described, as to either instrument, is complete of itself, and works the same in every respect; second, that while either in strument can be placed at a greater or less distance or height from the table or other support to which the telephonic stand is secured, and also can be swung about the usual line of the movement or adjustment just above stated that is, the vertical axis of the standard B- either instrument is also capable of being swung around two other axes (the axes of the joints R U) at a distance from each other, both of which axes are parallel to each other, and also to but not coincident with the axial swing and adjustment of the instrument first above stated, and, in addition thereto, either instrument is also capable of being swung around two other axes (the axes of the joints S T) at a distance from and parallel to each other, and at right angles to each and all the other axes above referred to.

Among special advantages of the telephone stand or support of thisinvention, in addition to its general and other capabilities before recited, it may be well to mention, first, that the telephonic instruments and their connections, when not in use, can be swung to the rear or either side of the standard B, and thus placed out of the way; second, that the double joints of the telescoping rods at each end,

as described, are in the nature of universal joints, and as a consequencein whatever positions the instruments may be placed by swinging them upon said joints and otherwise adjusting them, a then slight movement of the joints enables the instruments to be placed squarely to the mouth or car, as the case may be, and without necessarily changing the height or distance of the whole apparatus for its point of fixture to the table, wall, &c.; third, as the instruments are at the outer ends of their respective carrying-arms and jointed thereto, as described, when placed in position for use there are no obstructing arms in the way of the operator, and, again, the instru ments can be swung and placed under the carrying-arms, so as to leave a clear space below; fourth, by a simple movement of the parts carrying the instruments the position of the instruments can be readily changed for the receiver to be used at either the right or left ear of the operator, and for the transmitter to be placed in suitable relative position.

The washers for the working-joints, herein described, may be dispensed with; but they are desirable, as they enable sufficient friction to be given to the working-faces of the joints to hold the joints against accidental working and without tightening the parts together to an extent to prevent their being easily worked.

The telescoping of the rods may be dispensed with; but it is best to so make them. The carrying-arm for either instrument may be doubly jointed, as described, only at one and either end, instead of at both ends. The double jointing of the carrying-arm for either instrument may be used in connection with means for elevating and lowering their carrying-arm other than the screw-rod D and screwnut E. ing the stand or supportto wit, the screwrod D and screw-nut E-may be used with other means of connection of the instruments therewith. The standard 0 may be secured to the wall of a room, &c., in lieu of a table, and such standard may be of other formsas, for instance, if it is to be attached to awall in The means for elevating and lowerthe form of abracket, arranged to swing upon the walland other obvious changes and combinations of the several parts which have been herein described so fully may be made, and yetsecure more or less of the results aimed at by the present invention. However, a tele phone stand or support having all the parts and operations and movements specified is most desirable, for manifest reasons.

In conclusion, it will be observed that although the present improved stand or holder has been herein particularly described in con nection with telephonic instruments, and in the claims also particularly so stated, such description and claims are meant to and do include any and all other instruments for which said stand or support may be found available-as, for instance, microscopic instruments, &c.and so, therefore, it is not intended that this invention, either in its description or in the recital of the claims shall be limited to telephonic instruments only.
